ROBE-CLAMP.

Specification of LettersPatent.

Patented Apr. 26, 1921.

Application filed J'anuary12, 1921. Serial No. 436,648.

To all whom it may concern:

Be it known that 1, WILLIAM G. STRETCH, a citizen of the United States of America, residing at Washington, in the District of Columbia, has invented certain new and useful Improvements in Robe-Clamps, of which the following is a specification.

This invention relates to clamps and has special reference to a robe clamp for use in holding robes securely on the robe rails of automobiles and for preventing the theft of such robes.

One important object of the inventionis to provide an improved and simplified form of clamp for this purpose.

A second important object of the invention is to provide a novel arrangement of means for drawing the sides of such a clamp together. v

A third important object of the invention is to provide an improved arrangement of clamp and lock for this purpose.

With the above and other objects in view, as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings, and specifically claimed.

In the accompanying drawings, like characters of reference indicate like parts in the several views, and

Figure 1 is a side view of the device closed on a robe and robe rail.

Fig. 2 is a side view of the device inits open position. 7 j i Fig. 3 is a section on the line III-III of Fi 1.

l li 4 is a detail section on the line iv i v of Fig. 1.

Fig. 5 is a section on the line V-V of Fig. 4:.

Fig. 6 is a view showing the keys used herewith.

In the form of the device herein shown there is provided a body portion in the form of a yoke having a semicircular central part and legs 11 terminating in inwardly extending loops 12 forming gripping jaws. On the inside of each leg 11 is secured a lug 13 carrying a pivot bolt 14; to which is pivoted one end of an S-shaped link 15, the two links facing in opposite directions; Each of these links is secured to a disk 16 in the form of a hollow cylinder or look casing, the links being pivoted thereto by pivot bolts 17. lhis disk carries a projecting polygonal head 18 whereon may fit 'a key 19 so that the disk can be rotated to move the parts from the position shown in Fig. 2 to the'position shown in Fig. 1. In the latter position it will be observed that thelink ends pivoted to the disk interlock in jamming position and that the lug or projection 18 forms a stop in connection with one of the links to limit further movement. I

a In order to lock the device there is contained in the casing a revolving lock 19 the details of which are of any preferred type and are not deemed necessary here to be shown. The revolving part or barrel of this lock carries an eccentric 20 which is surrounded by an eccentric strap 21 having a beveled tongue 22 constituting the locking bolt.- W'ithin the casing is arranged a looking pin 28 constantly urged outward through an opening in the casing by a spring 24 sothat it may engage, when the parts are in the position shown in Fig. l, with a recess 25 in one of the links. The tongue 22 is so engaged in the pin 23 that the beveled por tion of the tongue, when forced forward by rotation of the eccentric 20, will force the pin inward and to so rotatethe look a key 26 is provided which maybe inserted through an opening 27to engage with said lock.

There has thus been provided a simple and efiicient device of the kind described and for the urpose specified.

aving thus described the invention is claimed as new is:

1. In a device of the kind described, a

what

clamp consisting of a pair of legs connected for yieldable movement toward each other,

. gripping aws on the ends of said legs,,links each having one end connected to a respective leg, a rotatable disk between said legs, pivot connections between the remaining ends of said links and substantially vdiametrical points on the disk, means carried by the disk for rotating said disk, said means constituting a limit stop engageable by one of the link 2. In a device of the kind described, a pair of legs yieldably connected for movement toward each other, gripping jaws on said legs, S-shaped links each having one end connected to the inside of a respective leg in spaced relation to its gripping jaw, a disk between said legs, pivot connections between diametrical opposite points on the disk and the other end of each link, said links being arranged with their curvature oppositely disposed whereby rotation of the disk interlocks the ends of the links connected. thereto, and a polygonal projection extending from one side of the disk and forming means to receive a turning key, said projection being positioned to further constitute a stop in connection with one of the links and thereby limit rotation of the disk.

3. In a device of the kind described, a pair of legs yielda-bly connected for movement toward each other, gripping jaws on said legs, S-shaped links each having one end connected to the inside of arespective leg in spaced relation to 1ts grlpplng aw, a disk between said legs, plvot connections between diametrical opposite points on the disk and the other end of each link, said links being arranged with their curvature oppositely disposed whereby rotation of the disk interlocks the ends of the links connected thereto, a polygonal projection extending from one side of the disk and forming means to receive turning key, said projection being positioned to further constitute a stop in connection with one of the links and thereby limit rotation oi the disk, and a lock carried by said disk and releasably engageable with one of said links in its interlocked position.

In testimony whereof I affix my signature.
